Order: Araneae

Family: Loxoscelidae

The Brown Recluse is sometimes called a "fiddleback" spider because of the dark violin shaped markings on its back. Brown Recluse spiders are found throughout the United States.

Description: Brown Recluse adults are about 1/4" to 1/2" in length. They range in color from tan to dark brown with markings on their back. A positive identification of this pest should be made by experts, as species differences need to be determined with a high-powered microscope.

Biology: The female Brown Recluse spider spins a non-uniform shaped web in sheltered areas. Unlike the Black Widow, the web is not used to catch prey, but is used as a haven. Brown Recluse spiders can produce a painful bite. Their venom can cause severe symptoms including fever, restlessness, inability to sleep and ulcerated tissue in the bite area. If you suspect this type of spider bite, seek immediate medical attention, and bring the spider with you if possible.

Habits: The Brown Recluse spider prefers quiet sheltered areas. Outside they may be found around rocks, wood piles, utility boxes, or under bark. Inside they can be found hiding in storage areas, undisturbed corners, under furniture, attics and crawl spaces. They typically run for cover when disturbed.
